Abstract Costunolide and its derived C-16 germacranolides on oxidation with selenium dioxide-t-butyl hydroperoxide afforded two melampolides, an aldehydolactone and the corresponding hydroxylactone, in each case. Structures were assigned to these melampolides on the basis of spectral data and chemical correlation. The aldehydolactones were significantly more active root promotors than their parent
摘要 Costunolide 及其衍生的 C-16 Germacranolide 用二氧化硒-叔丁基氢过氧化物氧化,在每种情况下都提供两种三聚氰胺,一种醛内酯和相应的羟基内酯。根据光谱数据和化学相关性为这些三聚氰胺分配了结构。醛内酯是比它们的亲本内酯更活跃的根促进剂。Costunolide 和相关的germacranolides 在用碘和氯铬酸吡啶处理后进行环化,得到有趣的产物。(-)-β-Frullanolide 已被合成并显示与其母体反式内酯相比具有更高的生物学活性。
